8506 Background: STaMINA was a phase III trial comparing progression-free survival (PFS) among 758 pts randomized to: 1. second autoHCT then lenalidomide (Len) maintenance (Auto/Auto, n = 247); 2. consolidation with Len/bortezomib/ dexamethasone (RVD) followed by Len maintenance (Auto/RVD, 254); 3. Len maintenance (Auto/Len, 257). All three arms were similar (Stadtmauer JCO 2018). Len maintenance was designed to continue for 3 years and amended to allow continuation until disease progression through a follow up protocol (07LT, NCT#02322320). We report 6 yr follow up for STaMINA and the results of Len discontinuation beyond 3 years. Methods: 07LT was offered to pts who were progression-free at 38 mo; completed planned Len maintenance and were within 4 years of BMT CTN 0702 follow up. Among 431 07LT eligible patients, 273 enrolled and 179 opted to continue maintenance until disease progression. All patients enrolled in STaMINA were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) and long-term outcomes for patients not enrolled on 07LT (N = 166) were available through this mechanism. Before combining 07LT data and CIBMTR data for LTFU analysis, outcomes in both databases were analyzed separately and confirmed to be comparable. Results: Using intent-to-treat (ITT), 6yr PFS and overall survival (OS) was the same among Auto/Auto (43.9%; 73.1%), Auto/RVD (39.7%, 74.9%) and Auto/Len (40.9%, 76.4%)(p = 0.6; p = 0.8). Protocol defined high risk disease, (HR = 1.53, p < 0.0001) and age (p = 0.03) were adverse risks for PFS. In as treated analysis, 6yr PFS were 49.4%, 39.7% and 38.6% for Auto/auto (170), Auto/RVD (222) and Auto/Len (361), respectively (p = 0.01). 6yr PFS in high risk pts as treated analysis were 43.6% and 26% for Auto/auto and Auto/Len, respectively (p = 0.03). Landmark analysis at 38 mo included 215 pts who continued Len maintenance (either on 07LT study or commercial Len) vs. 207 who stopped. Baseline demographics; study arm on 0702, induction pre-autoHCT were similar. Len discontinuation after 38 mo was associated with inferior PFS (79.5% vs. 61% at 5yr; HR = 1.91, p = 0.0004) but similar OS. Incidence of all second primary malignancies (SPM)(81 cases with 43 heme-malignancies) was associated with age. Conclusions: Long term outcomes are similar using ITT, but as treated analysis suggested a PFS benefit for tandem autoHCT, driven mainly by pts with high risk MM. Len discontinuation even at 38 mo was associated with inferior PFS. Clinical trial information: NCT02322320 .

Abstract Allogeneic hematopoietic cell transplantation (alloHCT) is a curative therapy for high-risk acute lymphoblastic leukemia (ALL). However, long-term outcomes after alloHCT for adult ALL have not been well described. We conducted a retrospective cohort study of 72 consecutive adult ALL patients who underwent a first myeloablative alloHCT at our institution from January 2000-December 2013. Median age at HCT was 38 yrs (range, 18-62), 40 (56%) were male, 18 (38%) had high HCT CI score, 14 (19%) had prior CNS leukemia and 35 (49%) had BCR-ABL+ disease. Donor source was HLA-matched related donor for 50% patients and 90% received PBSC as graft source. All patients were transplanted in CR (72% were in 1st or 2nd CR) and 92% received T-cell replete grafts. Median time from diagnosis to alloHCT was 5 months (range, 2-90). The incidences of grade II-IV and III-IV acute GvHD, chronic GvHD and extensive chronic GvHD were 43%, 13%, 51% and 36%, respectively. The median follow-up for our cohort is 76 months. At 6 years after HCT, probability of overall survival (OS) was 33% (95% CI, 21-44%) and relapse-free survival (RFS) was 30% (95% CI, 19-42%), and the cumulative incidence of relapse was 36% (95% CI, 25-48%) and non-relapse mortality (NRM) was 37% (95% CI, 26-49%). The most common causes of death were relapse (43%) and infection (21%); majority of relapses occurred within the first 2-years post-transplantation. There were no second cancer related deaths. In multivariable analyses, factors significantly associated with OS were HCT CI score (HR 2.69 for high vs. low/int., P=0.002) and CMV status (HR 2.62 for donor+ vs. others, P=0.05). HCT CI score was the only predictive factor for RFS (HR 2.26 for high, P=0.007). We also compared outcomes by BCR-ABL status. BCR-ABL+ patients were older (median age 42 vs. 36 yrs, p=0.02), had low HCT CI score (34% vs 22%, p=0.01), were more likely to be in CR1 (74% vs. 32%, p=0.002), and as a result, proceeded to HCT sooner after diagnosis (median 4 vs 7 months, p=<0.001). For BCR-ABL+ and BCR-ABL- patients, 6 year OS was 41% and 25%, RFS was 40% and 21%, relapse was 27% and 45% and NRM was 38% and 36% (P=NS for all comparisons). Myeloablative alloHCT can provide long-term survival for selected high-risk adult ALL patients. Relapses are relatively uncommon after 2 years post-transplant. Long-term NRM is high in this population and we did not observe a plateau in its incidence until 7.5 years post-transplant, suggesting the need for long-term follow up to prevent and manage late complications of alloHCT.

7033 Patients (pts) with high risk (HR) or advanced myeloid malignancies have limited effective treatment options. These include high-dose therapy followed by allogeneic hematopoietic cell transplantation (HCT). We report a single institution long-term follow-up of 96 pts, median age 50 (20–60) yrs, who received HLA matched related HCT between 1992 and 2007. All pts were treated with a uniform preparatory regimen: busulfan 16.0 mg/kg (d-8 to-5), etoposide 60mg/kg (d-4), cyclophosphamide 60mg/kg (d-2), and graft-versus-host-disease (GVHD) prophylaxis of cyclosporine and prednisone. Disease status at transplantation was induction failure (IF) acute myeloid leukemia (AML) (n = 10), HR AML in 1st complete remission (CR1) n = 11, in CR2 (n = 5), in CR3 (n = 2), relapsed refractory (RR) AML (n = 14), chronic myeloid leukemia (CML) in second chronic phase (n = 6), blast crisis (n = 2), myelofibrosis (n = 6), myeloproliferative disorders (n = 2), and MDS (n = 38). Thirty-six % (n = 35) of pts received bone marrow while 64 % (n = 61) received G-CSF mobilized peripheral blood mononuclear cells (PBMC). With a median follow up of 5.6 yrs (1.6–14.6 yrs) actuarial 5-year overall survival (OS) was 32% (95% CI 22–42%) and 5-year probability for freedom from progression (FFP) was 64% (95% CI 52%-76%). Relapse rate was 32% at 1 year and remained at 36% (95%CI 24%-48%) at 2 and 5 years with no further increase in relapse beyond two years. Non-relapse mortality (NRM) was 29 % (95% CI 20%5–38%) at day 100 and 39% (95% CI 29%-49%) at one yr. Cumulative incidence of acute (grade 3–4) and chronic GVHD was 28% (95% CI 19%-37%) and 38% (95% CI 24%-52%), respectively. There was no statistically significant difference in OS; 31% versus 32% (p = 0.89) or FFP 71% versus 60% (p = 0.29) for recipients of BM versus PBMC with similar results in IF and RR AML. These results confirm that pts with high-risk or advanced myeloid malignancies can achieve long-term survival following myeloablative allogeneic HCT with aggressive conditioning. Relapse and acute GVHD remain significant causes of mortality. Strategies to augment graft-versus-tumor reactions and reduce GVHD remain essential for improving long-term outcomes. No significant financial relationships to disclose.

6032 Background: A phase III multicenter prospective randomized controlled trial was conducted to compare cisplatin plus 5-fluorourcil with or without docetaxel as first-line induction chemotherapy in the patients with locoregionally advanced nasopharyngeal carcinoma (LANPC). Here, we report on the long-term outcomes and late toxicities of the trial (NCT01536223). Methods: Patients with newly diagnosed LANPC, stage III-IV disease, Karnofsky performance score≥70, without metastasis were eligible and randomly assigned 1:1 to TPF versus PF for three cycles. The primary end point was progression-free survival; local control, OS and advent events were important key secondary end points. The Kaplan-Meier method and the log-rank test were used to conduct and compare the survival curves in this study. Results: Two hundred ninety-nine patients were enrolled. 276 patients (138 TPF and 138 PF) were evaluable. Baseline characteristics were well-balanced between two groups, and the median age was 48 (range, 18-60 years). The ORR rates after induction chemotherapy and chemoradiotherapy were 90.6% and 9797.8% in TPF group and 87.0% (P > 0.05) and 97.8% (P > 0.05), respectively. The median follow-up was 99 months. For all patients, the 5- and 8-year OS and PFS were 76.9% and 74.9%, 72.3% and 69.1%, respectively. PF was associated with a similar PFS versus TPF ( 5-year PFS of 72.4% versus 73.2%, P =.747), and an equivalent OS at 5 years ( 79.2% and 79.1%, P = 0.519). Treatment-related grade 3 to 4 advent events were less frequent with PF compared with TPF. Conclusions: With prolonged follow-up, the survival outcomes in the PF group were not non-inferiority to those in the TPF group, but grade 3 to 4 advent events were less frequent. Clinical trial information: NCT01536223.

Abstract BACKGROUND Between 1995 and 2002 the EORTC Brain Tumor Group conducted a prospective phase III study on adjuvant procarbazine, CCNU and vincristine (PCV) chemotherapy in anaplastic oligodendroglioma (AOD). A mature follow-up presented in 2012 showed survival benefit of the addition of PCV, in particular in 1p/19q co-deleted tumors and tumors with MGMT promoter methylation. We now present very long term follow-up. MATERIALS AND METHODS Patients were eligible if locally diagnosed with a newly diagnosed AOD. They were randomized between radiotherapy (RT, 33 x 1.8 Gy) and the same RT followed by 6 cycles PCV (RT/PCV). Primary endpoints were overall survival (OS) and progression free survival (PFS). 1p/19q status (FISH) was determined in 300 patient. Kaplan- Meier technique and Cox modeling were used for long term survival analysis. Primary analyses were adjusted for known prognostic factors. For other analyses no adjustment was performed. RESULTS With 368 patients included, a median follow-up of 18.4 years and 307 (83%) survival events, median and 20-year survival after RT/PCV versus RT alone were 42.3 mo and 16.8% vs 30.6 months and 10.1% (HR 0.78; 95% CI (0.63, 0.98), adjusted p=0.06). Eighty patients were 1p/19q codel of which 26 (33%) were still alive, in this subgroup median and 20-year survival after RT/PCV versus RT alone were 14 years and 37.1% versus 9.3 years and 13.6% (HR 0.60, 95% CI (0.35, 1.03), unadjusted p=0.06). Twenty year PFS in 1p/19q codel was 31.3% in RT/PCV treated patients and 10.8% in RT only treated patients (HR 0.49, 95% CI (0.29, 0.83), unadjusted p=0.007). In the 1p/19q codel subgroup age, WHO PS and necrosis at pathology were identified to be of independent prognostic value for OS. CONCLUSION This long term analysis confirms the earlier conclusions and provides data on long term survival in this patient group. In 1p/19q codel patients treated with RT/PCV, the 20-year PFS and OS rates are 31% and 37% respectively.

Abstract RIC with FM has extended the use of HSCT to patients otherwise not eligible for this treatment. Longer follow-up and larger number of patients now allow for more robust evaluation of risk factors and outcomes. Herein are the results of such an evaluation. Patients and Methods: We evaluated outcomes of 112 patients with high-risk AML/MDS treated from August 1996 to December 2003 with FM (fludarabine 100–180 mg/m2 and melphalan 100–180 mg/m2) and unmanipulated HSCT. Eligibility included age &gt;54 yrs. or comorbidity precluding an ablative preparative regimen. Disease status at HSCT was relapsed/refractory (n=43, 38.4%), primary induction failure (n=32, 28.6%), untreated (n=7, 6.3%) or complete remission (CR, n=30, 26.8). Cytogenetic risk was intermediate (n=59, 53%), high (n=47, 42%), low (n=3, 2.5%) or unknown (n=3, 2.5%). Donors were HLA matched related (MRD; n=59) or unrelated (UD; n=53). GVHD prophylaxis was tacrolimus based in all but one patient. Anti-thymocyte-globulin was added in 31 UD HSCT. Stem cell sources were bone marrow (n=56) or peripheral blood (n=57). Median age was 55 (range 22–74). Evaluated were the following variables and their influence on disease progression and overall survival: - age, donor type, duration of first CR, disease status at transplant (categorized as CR, No CR with (NoCR/CB) and without circulating blasts (NoCR/NoCB)), cytogenetics, acute and chronic GVHD (time dependent variables), and blood counts on day 30 (lymphocytes, monocytes and platelets). We used a Cox’s regression analysis. Results: Median time of follow up among survivors (n=43) was 28.4 mo (3.3–88.9). CR rate at day 30 post transplant was 87% (n=97), 8 patients died early and 7 did not respond. 25 (26%) of 97 patients progressed after day 30. All but 3 patients relapsed within the first year post HSCT, and only one relapsed more than 2 years after HSCT. In a landmark analysis, disease status at transplant was the only significant risk factor for progression among these 97 patients (HR of 3.7 for the NoCR/CB group compared to the CR group). 69 of 112 patients died with a median survival of 4.6 mo. Seven deaths (10% of all deaths) were observed more than 2 yrs. after HSCT, due to GVHD (n=3), infection (n=2), relapse (n=1) and unknown causes (n=1). Two-year OS and PFS was 44% and 69% respectively. Disease status at HSCT and grade II-IV aGVHD were the only significant predictors of OS on univariate and multivariate analysis. Blood counts on day 30 were associated with disease status at transplant, donor type and aGVHD. Their independent effect on outcome could not be evaluated given sample size. Conclusion: A significant portion of older patients with high-risk AML/MDS may achieve long-term PFS, but early relapses are the major cause of treatment failure in this context.

LBA5002 Background: High-risk, localized prostate cancer (PCa) patients have a relatively poor prognosis. We hypothesized that the addition of adjuvant docetaxel and prednisone to long-term (24 month) AS and radiation therapy (RT) would improve overall survival (OS). Methods: RTOG 0521 opened December 2005 and closed August 2009 with targeted accrual of 600 cases. It was designed to detect improvement in 4-year OS from 86% to 93% with a 51% hazard reduction (HR = 0.49). Under a 0.05 1-sided type I error and 90% power, at least 78 deaths were required to analyze the OS endpoint. Patients had 1) Gleason (Gl) 7-8, any T-stage, and PSA > 20, or 2) Gl 8, ≥ T2, any PSA, or 3) Gl 9-10, any T-stage, any PSA. All had PSA ≤ 150. RT dose was 75.6 Gy. CT consisted of 6, 21-day cycles of docetaxel + prednisone starting 28 days after RT. Results: Of 612 enrolled, 50 were excluded for eligibility issues, leaving 562 evaluable. Median age = 66, median PSA = 15.1, 53% had Gl 9-10, 27% had cT3-4. Median follow-up = 5.5 yrs. 4-yr OS rates were 89% [95% CI: 84-92%] for the AS+RT arm and 93% [95% CI: 90-96%] for the AS+RT+CT arm (1-sided p = 0.03, HR = 0.68 [95% CI: 0.44, 1.03]). There were 52 centrally-reviewed deaths in the AS+RT arm and 36 in the AS+RT+CT arm, with fewer deaths both due to PCa/treatment (20 vs 16) and due to other causes/unknown (32 vs 20) in the AS+RT+CT arm. 5-yr disease-free survival rates were 66% for AS+RT and 73% for AS+RT+CT (2-sided p = 0.05, HR = 0.76 [95% CI: 0.57, 1.00]). There was 1, Gr 5 unlikely-related adverse event (AE) in the AS+RT arm and 2, Gr 5 possibly/probably-related AEs with AS+RT+CT. Conclusions: For high-risk, localized PCa, adjuvant CT improved the OS from 89% to 93% at 4 years. Toxicity was acceptable. This trial was designed with a short OS assessment period and additional follow-up is warranted to determine the long-term benefit of CT to the current standard of care of long-term AS+RT. This project was supported by grants U10CA21661, U10CA180868, U10CA180822, from the National Cancer Institute and Sanofi with additional support from AstraZeneca for Australian site participation.

Object Although nucleus ventralis intermedius stimulation has been shown to be safe and efficacious in the treatment of essential tremor, there is a subset of patients who eventually lose benefit from their stimulation. Proposed causes for this phenomenon include tolerance, disease progression, and suboptimal location. The goal of this study was to assess the factors that may lead to both stimulation failure, defined as loss of meaningful tremor relief, and less satisfactory outcomes, defined as leads requiring voltages > 3.6 V for effective tremor control. Methods The authors present their clinical outcomes from 31 leads in 27 patients who had effective tremor control for > 1 year following nucleus ventralis intermedius stimulation. All patients postoperatively had a mean decrease in both the writing and drawing subscales of the Fahn-Tolosa-Marin Tremor Rating Scale (p < 0.001). Results After a mean follow-up of 40 months, 22 patients continued to have tremor control with stimulation. Four patients eventually lost efficacy of their stimulation at a mean of 39 months. There was no difference in age, duration of disease, or disease severity between the groups. Examination of perioperative factors revealed that suboptimal anteroposterior positioning as evidenced on intraoperative fluoroscopy occurred significantly more frequently in patients with stimulation failure (p = 0.018). In patients with less satisfactory outcomes, no difference was seen between group demographics. Fluoroscopy again revealed suboptimal positioning more frequently in these patients (p = 0.005). Conclusions This study provides further evidence that suboptimal lead position in combination with disease progression or tolerance may result in less satisfactory long-term outcomes.

4112 Background: Gender predicted for the most effective schedule in a RT of ChronoFLO vs CONV against MCC: overall survival (OS) was significantly increased in men on chronoFLO vs FOLFOX, whereas the reverse was found in women (Giacchetti, JCO 2006). Methods: To assess the relevance of gender for patient (pt) outcome, meta-analysis was performed on individual pt data (IPD) from 3 RT in 845 MCC pts treated with chronoFLO vs CONV (346 F, 499 M at 36 centers in 1990–2002)(Lévi, JNCI 1994; Lancet 1997). Data bases were merged and updated at 9 y after inclusion of the 1st pt. Main prognostic factors were comparable in each RT according to gender and treatment arm (median age: 61y; PS=0, 46% pts; liver M, 85% pts; liver involvement >25%, 41% pts; lung M, 37% pts; CEA>10, 56% pts). Results: No significant difference was found according to delivery schedule or gender in the whole population for Response Rate (RR), Progression-Free Survival (PFS) and OS. However, men on chronoFLO had highest RR, longest PFS and OS. PFS and OS were highest in women on CONV ( Table ). The rate of complete macroscopic resections of liver metastases (R0+R1) was 12.5% in men on chronoFLO vs 7.8–8.5% in men on CONV or in women on either schedule. A complete histologic response of liver metastases was documented in 2.1% of the men on chronoFLO vs 0–1.1% in the other groups. The relative risk of an earlier death in men vs women was 0.76 [95% CL, 0.91 to 0.94] on chronoFLO and 1.24 [0.99 to 1.56] on CONV. Conclusions: This IPD meta-analysis of 3 RT in MCC with a minimum follow up of 5 years confirms that men benefit from chronoFLO as compared to CONV delivery, with regard to long term outcome and medico-surgical strategy. ChronoFLO should be preferred to conventional oxaliplatin-5-FU-LV schedules in men with MCC. Support: ARTBC Internationale, P. Brousse Hospital, Villejuif, France.
